FREDERICK J'. WEBER, OF CONNERSVILLE, INDIANA, ASSIGNOR TO THE STEELSTORAGE AND ELEVATOR CONSTRUCTION COMPANY, OF SAME SWIVEL FOR PNEUMATICGRAIN-PIPES.

SPECIFICATION formingpart of Letters Patent No. 589,800, dated September7, 1897.

' Application filed June 21, 1397. Serial No. 641,583. (a model.)

To all whom may concern:

Be it known that I, FREDERICK J. WEBER, of Gonnersville, Fayette county,Indiana, have invented certain new and useful Im- 5 provements inSwivels for Pneumatic Grain- Pipes, of which the following is aspecification.

My invention relates to improvements in swiveling grain-pipes employedin moving grain by pn eumaticmeans, and the improvements will be readilyunderstood from the following description, taken in connection with theaccompanying drawings, in which- Figure 1 is a vertical section of myimproved swivel, and Fig. 2 a side elevation of the same in connectionwith an exemplifying grain-receiver from which the grain is to betransferred.

In the drawings, 1 indicates an exemplifying receiver, to be assumed ascontaining grain or granularmaterial which is to be transferredtherefrom by the means of an air-blast; 2, the pipe through which thedischarging grain is to pass from the receiver to the desired point ofdelivery; 3, an elbow forming the juncture between pipe 2 and thereceiver, the exemplification showing this elbow as connecting directlywith the receiver or, to speak more accurately, as having closeconnection with the receiver, which closeness is, however,

quite unimportant; 4, a valve disposed in the 3 5 its axis being atright angles to the axis of pipe 2, so that pipe 2 is thus capable ofturning about upon a vertical axis; 6, the air-pipe through which is tobe conveyed the blast of air which is to propel the grain forward in 7,an elbow forming a part of pipe 6 and having its vertical axis in theaxial line of swivel 5, the presence of elbow 7 as an elbow being merelyan incident to the fact that air-pipe 6 is illustrated as being disposedhorizontally; 8, a support for the upper portion of elbow 7, whichsupport, in the ordinary use of pneumatic grain-transfer apparatus, willbe a suitable deck or floor; 9, an elbow-nozzle extending from the upperend of elbow 7 into the base of elbow 3 and presenting its nozzle endtoward pipe 2, elbownozzle 9 and elbow 3 forming, in effect, an integral structure, and 10 a swivel at the juncture of elbow-nozzle 9 withelbow 7, the axis of this swivel coinciding with that of swivel 5.

The air-blast discharges into pipe 2 from the nozzle and carries with itthe grain coming down through elbow 3. Pipe 2 may be turned about in anydirection, turning now on the common axis of elbow and elbow- .nozzle 9.

away from said swivel-j oint, a swivel-joint at the base of saidelbow-nozzle and having its axis in line with that of thefirst-mentioned swivel, and an air-pipe connected with said elbow-nozzlethrough the medium of the lastmentioned swivel-joint.
